The Dote 1 occurrence is located approximately 1.7 kilometres east-northeast of Aspen Grove and 2.25 kilometres northeast of the north end of Kidd Lake.

Regionally, the area is underlain by the Upper Triassic Nicola Group, which regionally consists of alkalic and calc-alkalic volcanics and intrusions of island arc origin, and which is the principal component of the Quesnel terrane in southern British Columbia (Geological Survey of Canada Maps 41-1989, 1713A). The area lies in the Central Belt or facies of the Nicola Group (after Preto, Bulletin 69). This belt of rocks mainly consists of subaerial and submarine, red or purple to green augite plagioclase porphyritic andesitic and basaltic flows, volcanic breccia and tuff, and minor argillites and limestone. The volcanics are intruded by bodies of comagmatic Upper Triassic to Lower Jurassic diorite to monzonite. The area is characterized by long-lived, primarily north-striking faults and related fracturing, which originally controlled intrusion emplacement. East-striking faults are subordinate, and commonly offset intrusive contacts.

Locally, chalcocite and minor bornite occur as disseminations and as partial rims around calcite amygdules in massive green augite porphyry basalt of the Upper Triassic Nicola Group (Central Belt, Bulletin 69). Malachite and azurite are also present. This mineralization is exposed in two shafts, 70 metres apart.

In 1970, a grab sample of sheared basalt from the western shaft assayed 0.89 per cent copper, whereas dump samples from the west and east shafts yielded 1.35 and 0.19 per cent copper, respectively (Assessment Report 2468, page 15). The following year, a selected composite sample of dump material yielded 3.5 per cent copper, 0.03 gram per tonne gold and 51.3 grams per tonne silver (Assessment Report 3051, page 6).

An opencut, located approximately 140 metres northeast of the eastern shaft, exposes minor pyrite and malachite along joint planes in an andesite. In 1971, a chip sample assayed 0.2 per cent copper over a length of 1.8 metres (Assessment Report 3051, page 6).

In 2012, two subcrop rock samples (826-6A and -6B) of altered intermediate to mafic volcanics with finely disseminated bornite and malachite staining, located approximately 250 metres northeast of the shafts, yielded greater than 1.00 per cent copper, each, with 41.7 and 52.2 grams per tonne silver, respectively (Assessment Report 33851).

Work History

Two shafts, likely dating to the early 1900s, were developed on the occurrence.

During 1969 through 1972, Dawood Mines Ltd. and Amax Exploration Inc. conducted programs of geological mapping, soil sampling, ground magnetic and electromagnetic surveys and 12 drillholes on the area as the Dote claims.

In 1991, Northair Mines Ltd. completed a program of rock and soil sampling on the area as the Shear property. The following year, Placer Dome Inc. completed a program of geological mapping, trenching and soil sampling on the property. In 1993, Northair Mines Ltd. completed a further program of rock sampling on the property. In 1997, Christopher James Gold Corp. completed a program of geological mapping, geochemical (rock and soil) sampling and a 13.8 line-kilometre induced polarization survey on the area as the Big Kidd property.

In 2008, Christopher James Gold Corp. completed a 1113.5 line-kilometre airborne magnetic-radiometric survey on the Big Kidd property.

In 2011 and 2012, Xstrata Copper Canada Corp., on the behalf of Jiulian Resources Ltd., completed programs of prospecting, geochemical (rock and soil) sampling and a 56.8 line-kilometre induced polarization survey on the Big Kidd property. In 2018, Jiulian Resources Ltd. completed an 84.0 line-kilometre ground magnetic survey on the Big Kidd property. The following year, an 18.0 line-kilometre induced polarization survey was completed.
